A month ago I installed Windows 7 Pro on a new Asrock MB. The only modified bios I could find was a flash from Windows Asus version. Everything worked fine until now. Now I get the non genuine messages. I loaded AIDA64 and saw there was no SLIC entry in the bios. I reflashed with the same bios I used before and rebooted. All is well and AIDA64 shows the SLIC entry for now at least. When I installed Windows 7, I used an all in one version that will only install a loader if there is no SLIC in the bios. Then I flashed the modified bios. I installed Windows twice. The first time was to flash the bios. I then formatted the drive a second time to get rid of the boot loader and to install Windows with a "modified" bios. So my question is. Will the Windows bios flash utility work properly if Windows was running with a boot loader? BTW I never got the 30 days to activate notice. Maybe one of you can explain what happened.
